Fuel pump wiring problem - Racing Forum

The fuel pump has just stopped working in the car I am building. I tried putting power directly to the gray wire and I still have nothing with the key on or off. What does the purple and black wires do? Do either of them need power or ground? What has other people done?

i will cut the black wire and ground it out so I don't run into anymore problems. If I got to drop the tank on this thing I am going to just cut a hole in the floorboard and run the wires through it and just cover it with a piece of sheetmetal so I don't have to drop the tank if the wiring messes up or the fuel pump were to go bad...
